Just do it! I started a DWR with the McCall's pattern a couple of years ago and haven't finished (just because of competing priorities), but I sure conquered the curved seams while working on it. The only way to the other side is through. You can do it!
QuiltSmart is a fairly new product which people are using to make the Double Wedding Ring Quilt. You should look into it, I hear it is easy. Quilters Common in Wakefield, MA has been giving classes in it using the QuiltSmart. Good luck!
@ post #10: cad_queen_2000: That is a very pretty quilt and I love the colors you used. I am anxious to make one of my own some day.
